The Riverside Inn was a hotel and dinner theater in Cambridge Springs, Crawford County in the U.S. state of Pennsylvania. Built in the late-1880s at the height of the mineral springs craze in the United States, it was operated as a resort for vacationers heading to the nearby springs that gave Cambridge Springs its name. The Riverside Inn was the first of many resorts to be built during that period. It was listed on the National Register of Historic Places in 1978. The Riverside Inn was destroyed by fire in the early morning of May 2, 2017.
